Ay, mama, that's something you really need to bring to your pedia asap, loaded bacteria in stool can mean infection or imbalance, and one-year-olds need proper testing to know what's causing it and kung kailangan ng treatment. I'd get the stool test results checked with a doctor kaagad para ma-identify kung ano exactly ang bacteria at kung paano ma-treat, kasi self-treating dito ay risky talaga for littles.
